“For most people, increasing age is the biggest risk factor for developing cancer,” warns Macmillan Cancer Support.
The charity says: “In general, people over 65 have the greatest risk of developing cancer. People under 50 have a much lower risk.”
The biggest modifiable risk factor is smoking, which accounts for more than one in four cancer deaths in the UK.
“Being overweight increases the risk of many types of cancer, including cancers of the bowel, kidney, womb and gullet (oesophagus),” warns Macmillan Cancer Support.
